Met an interview today, I now is to do the oracle database development, the interviewer is the head of their database, ask the question very wonderful work, ask what I do, I say is oracle database development, and then ask what language I use, I was speechless, oracle database development also can use what language? Then let me talk about problem encountered in the database development, more speechless, PLSQL this is not difficult language, in addition to some performance related considerations can want how to just write according to company development specification, suddenly forget a function most grammar under Internet, database development difficult because database development must be familiar with the company's business, is not difficult to write SQL

CodePudding user response:

Sometimes the Java, python code for the development of god can be called database development - don't even see you write a program to DB, do you want to run the SQL

You understand database development is focused on the development of PL/SQL? Do the ETL, for example,

Above are not strange flower, wonderful work is: the company all don't know oneself recruit interviewer is what job?

CodePudding user response:

You said that the development direction of the DBA, there should be no problem,

CodePudding user response:

Don't wonder, Java, python,.net, c, c + +, COBOL can deal with oracle, he want to know what you are developer, not surprisingly,
Database development, basically be the SQL, SQL to write is not good, that is a pile of performance problems, didn't write well also may have functional problems,
